I need help with the questions

Step-by-step explanation:

Hello

please find attached the graph

you can notice that

(a) from the graph we can say that there is no maximum and one minimum in x = 3

and then f(3) = 0 so o is the minimum of f

(b) vertex is (3,0)

(c) x = 3 is an axis of symmetry

(d) as the root is 3

(e) y=9 for x = 0 so the y-intercept is 9

do not hesitate if you need further explanation

if you like my answer, tag it as the brainliest :-)

answer: a

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
